Thaum qhov loj me ntawm Fe2O3Hlau (III) oxideyog me me rau nanometer (1 ~ 100nm), qhov chaw atomic naj npawb, thaj chaw tshwj xeeb thiab lub zog saum npoo ntawm cov hlau oxides nce sharply nrog qhov txo qis ntawm qhov loj me, uas qhia tau hais tias cov yam ntxwv ntawm cov nyhuv me me, cov nyhuv quantum loj, nto cov nyhuv thiab macroscopic quantum tunneling nyhuv. Nws muaj cov khoom siv kho qhov muag zoo, cov khoom sib nqus thiab cov khoom siv catalytic thiab lwm yam, uas muaj cov ntawv thov dav hauv thaj chaw ntawm lub teeb nqus, tshuaj, sib nqus media thiab catalysis.
1. Kev siv cov nano-hlau oxide hauv cov ntaub ntawv sib nqus thiab cov ntaub ntawv sib nqus
Nano Fe2O3 muaj cov khoom sib nqus zoo thiab zoo hardness. Cov ntaub ntawv oxymagnetic feem ntau suav nrog cov hlau nplaum hlau oxide (α-Fe2O3) thiab cov ntaub ntawv sib nqus hlau oxide (γ-Fe2O3). Sib nqus nanoparticles muaj cov yam ntxwv ntawm ib leeg sib nqus domain qauv thiab siab coercive quab yuam vim lawv qhov me me. Kev siv lawv los ua cov ntaub ntawv sau sib nqus tuaj yeem txhim kho lub teeb liab-rau-suab nrov piv.
2. Daim ntawv thov ntawmnano hlau oxidenyob rau hauv cov xim thiab coatings Nyob rau hauv pigments,nano hlau oxidetseem hu ua pob tshab hlau oxide (hlau nkag). Lub npe hu ua pob tshab tsis hais tshwj xeeb rau cov macroscopic transparency ntawm cov khoom lawv tus kheej, tab sis hais txog kev tawg ntawm cov xim xim hauv cov txheej txheem organic los ua cov txheej xim xim (lossis cov yeeb yaj kiab roj). Thaum lub teeb yog irradiated ntawm cov xim zaj duab xis, yog tias nws tsis hloov qhov qub Los ntawm cov xim zaj duab xis, cov xim xim tau hais tias yog pob tshab. Cov pob tshab hlau oxide xim muaj chroma siab, siab tinting zog thiab siab transparency, thiab muaj kev sib tsoo zoo thiab dispersibility tom qab tshwj xeeb nto kho. Pob tshab hlau oxide pigments tuaj yeem siv rau oiling thiab alkyd, amino alkyd, acrylic thiab lwm yam xim los ua cov xim pob tshab, uas muaj cov khoom zoo nkauj zoo nkauj. Cov xim pob tshab no tuaj yeem siv ib leeg lossis sib xyaw nrog lwm cov xim organic xim pastes. Yog hais tias ib qho me me ntawm cov hmoov txhuas uas tsis yog-floating hmoov muab tshuaj ntxiv, nws tuaj yeem ua rau hauv cov xim hlau xim nrog lub siab flickering; Nws yog txuam nrog primers ntawm cov xim sib txawv, tuaj yeem siv rau hauv cov khoom siv kho kom zoo nkauj nrog cov kev xav tau siab, xws li tsheb, tsheb kauj vab, twj paj nruag, meters, thiab khoom siv ntoo. Cov xim hlau xa tawm cov xim muaj zog nqus ntawm ultraviolet lub teeb ua rau nws yog ib qho ultraviolet shielding tus neeg sawv cev hauv cov yas, thiab siv rau hauv ntim cov yas xws li dej haus thiab tshuaj. Nano Fe2O3 kuj muaj cov ntawv thov dav dav hauv electrostatic shielding coatings, thiab Fe3O2 nano coatings nrog zoo electrostatic shielding tau tiav lawm. Xws li nanoparticles nrog cov khoom siv hluav taws xob muaj cov khoom siv hluav taws xob ntau dua li cov pa oxides ntawm chav tsev kub, thiab yog li tuaj yeem ua lub luag haujlwm tiv thaiv electrostatic.
3. Kev siv nano-hlau oxide catalyst Nano-iron oxide yog ib qho catalyst zoo heev. Hollow spheres ua los ntawm nano-α-Fe2O3 yog ntab rau saum npoo ntawm cov dej khib nyiab uas muaj cov organic teeb meem. Siv lub hnub ci kom degrade organic teeb meem tuaj yeem ua kom cov txheej txheem dej khib nyiab. Txoj kev no yog siv los ntawm Tebchaws Meskas, Nyij Pooj, thiab lwm yam los daws cov pa phem uas tshwm sim los ntawm ntug dej hiav txwv roj. Nano-α-Fe2O3 tau siv ncaj qha los ua ib qho catalyst rau oxidation, txo thiab synthesis ntawm siab molecular polymers. Cov nano-α-Fe2O3 catalyst tuaj yeem ua kom cov roj av tawg ntawm 1 mus rau 5 zaug, thiab qhov kub ceev ntawm cov khoom siv hluav taws xob ua nrog nws ua cov khoom siv hluav taws xob tuaj yeem nce los ntawm 1 txog 10 npaug piv rau qhov kub ceev ntawm cov khoom siv hluav taws xob zoo tib yam. . Cov foob pob hluav taws thiab cov foob pob hluav taws muaj txiaj ntsig zoo heev.
